msm: mhl: hdmi: MHL-HDMI handshake implementation
By default, HDMI driver adds entries for
all the formats that it supports into an internal table.
However, when MHL Tx is present, the max format
supported should be limited based on the maximum bandwidth
supported by the MHL Tx. We implement a handshake between
HDMI and MHL drivers to exchange callback function which
returns the status of HDMI's TMDS lines that is used by MHL
driver before sending RAP messages.
